Custom software engineering · 06

What off-the-shelf can't do · we ship end-to-end.

Most real projects aren't SaaS-splittable · embedded firmware, factory-line software, IoT platforms, internal ERP integrations. We look at the hardware, the line, the process, then ship.

WHAT WE SOLVE

[1/8]

What we solve

  • 01Off-the-shelf software solves 80% · the 20% is the pain
  • 02The ERP-linked internal tool nobody maintains
  • 03The embedded team quit · nobody knows the code anymore
  • 04IoT fleet with no OTA · manual updates every time

What we ship

  • The 20% pain stitched into the existing 80%
  • ERP / factory-line integration, documented and tested
  • Embedded code · Git, CI, signed firmware, OTA
  • IoT fleet · remote update, telemetry, service mode

WHAT YOU GET

[2/8]

01

Embedded / firmware (C, Rust, MicroPython)

02

IoT system · device + cloud + app together

03

Desktop app (Electron, Tauri, native Swift/Kotlin)

04

Custom integration (ERP, SCADA, factory line)

05

Manufacturing / internal operational tooling

HOW WE WORK ON THIS

[3/8]

How we work on this

The same risk-reducing rhythm on every project · each step has a measurable deliverable.

01

Discovery

Hardware / infra walkthrough · existing code, docs, operators, interfaces. On site, not over email.

02

Scope + risk matrix

What happens if we're wrong. What's offline, what's online. Risk matrix + rollback plan, before a line of code is written.

03

Iterative delivery

Every release auditable, revertable. Firmware versioned, signed, OTA-delivered. Blue/green for the factory floor.

04

Ops + handover

Runbooks, training, 3 months post-launch support. The internal team takes over; we don't become the single point of failure.

COMMON QUESTIONS

[5/8]

Common questions

What most people ask · answered before you have to.

Correct. We work with hardware (ESP32, STM32, Raspberry Pi, industrial PLCs), but we don't design circuits. If you need that, we'll recommend a partner.
